Extracted text: 6(b) Consider the following situation described by A.K. Sen in Collective Choice and Social Welfare: Let the social choice be between three alternatives involving Mr. A reading a copy of Lady Chatterley's Lover, Mr. B reading it, or no one reading it. We name these alternatives a, b, c, respectively. Mr. A, the prude prefers most that no one read it, next that he reads it, and last the impressionable Mr. B be exposed to it, i.e. he prefers c to a ,and a to b. Mr. B, the lascivious, prefers that either of them should read it rather than neither, but further prefers that Mr. A should read it rather than he himself, for he wants A to be exposed to Lawrence's prose. Hence he prefers a to b, and b to c. How should society rank these alternatives so that the ranking is consistent with Pareto optimality?
